The real-life photos (and a few insights into their lives after the events in the movie) of Dr. Donald Shirley and Frank "Tony Lip" Vallelonga are shown before the end credits roll.
"Larry the Crow" gets a mention. This was an actual crow that Viggo Mortensen found injured near the set, and tried in vain to nurse back to health. He was no doubt named for Viggo's favorite soccer team, San Lorenzo (Saint Lawrence in Spanish). The team nickname is "The Crows".
